The reclaimed territory is level and excellently drained.
By 1710 30 acres more had been reclaimed or bought, and by the end of the 18th century the total area was 90 acres.
The soil when reclaimed is well adapted for forage crops, cereals, vegetables and deciduous fruits.
The ground on which the port is built has all been reclaimed from the sea.
Since the beginning of the 20th century large sums have been borrowed and expended on new avenues, the widening and straightening of old streets, and the improvement of the water-front between the Passeio Publico and the southern extremity of the Praia de Botafogo by the construction of a grand boulevard, partly on reclaimed land.
